Help with MODBUS
« on: April 01, 2015, 02:20:35 PM »
I'm trying to establish a Modbus tcp connection between AdvancedHMI and a PTV from Red Lion Controls and its works, but, when I map the Modbus addresses it does not read the correct value.

if I only use a single BasicLabel it works, but when I try to use more than one BasicLabel (with diferent floating point it only read an address but the an others don't.

I hope you understand me.

Floating point uses 2 words, so address F40010 and F40011 overlap. You can only use F40010 and F40012
